Jams, slow traffic, closures and roadworks in force this minute on up to 5 motorways, with delay/speed. Use when asked about a named motorway now: Stau, a delay, how it looks, or a LIST of closures now; name every motorway (Munich→Berlin: A9). Do NOT use for yes/no: is a road open/closed/passable — check_road_status, even now — nor a closure with no time word or a later one (tonight, weekend); Bau

Returns the cheapest stations for one fuel grade near a place or coordinate: price per litre, brand, address, distance, open state. Use when the user asks where to fill up or what fuel costs. Do NOT use for charging an electric car (call find_charging_station), price history, or traffic (call check_autobahn_traffic). Radius ≤ 25 km, at most 10 stations. For a brand, a name, open now or at a named

Finds filling stations around a place or coordinate under any combination of filters — grade, brand, name, open now, open at a time you name, open 24 h — sorted by distance, price or name. Use when the question is WHICH station: the closest diesel to a stop, an ARAL open tonight, what one forecourt sells.

Parking near a place, a coordinate or along one motorway: motorway lorry parks, car parks and P+R sites, with total spaces and, where published, free spaces now and the reading's age. Use when asked where to park or leave the car for the train ("Parkhaus in Köln", "Rastplatz A3", "P+R"). Do NOT use for fuel (find_cheapest_fuel) or EV charging (find_charging_station).

Returns roadworks PLANNED on one motorway, one Bundes-/Landesstraße in NI, SN, TH or BW, or Hamburg city streets by place, in a date window: section, restriction, dates. Use when a date or window is named, it says geplant, or how long a site lasts ("Baustellen auf der A7 in den Sommerferien?"). ONE road/place per call. Do NOT use when more than one motorway is named, for the situation this minute,

Looks up a place name and returns every place that matches, each with its kind, official key (AGS/RS), population, English name and coordinate. Use when the person asks where somewhere is, when you need a coordinate for another tool, and above all to RECOVER after a tool reported a name as ambiguous — this is where you find out which Neustadt is which.

query	string	yes	The place name to look up, as the person said it — "Neustadt", "Munich", "Kreis Fulda", "Köln Hbf". English names and spellings without umlauts both work.
kind	string	no	Narrow to one kind: "city", "district" (Kreis), "admin" (Land or Regierungsbezirk), "station", "stop", "motorway" or "junction". Omit unless the person was specific.
near	string	no	A second place to measure from, used to tell same-named candidates apart: "Neustadt" near "Hamburg" is one of twenty Neustadts. Every result then carries its distance from this point.
lat	number	no	Latitude to measure from, instead of near.
lon	number	no	Longitude to measure from, instead of near.
radius_km	number	no	When near/lat+lon is given, keep only candidates within this many kilometres (1–200). Omit to rank by distance without dropping any.

Finds a business or landmark by name or kind — company, shop, clinic, hotel, hostel — with address, category and coordinate. Use when the person names a THING rather than a town: "the adesso office in Dortmund", "the nearest Aldi", "a hotel in Weimar". The coordinate passes to any other tool as lat/lon.

in	string	no	A town to search in — "Dortmund", "Fulda". Strongly preferred: it is both far faster and far less ambiguous than a nationwide search. Use this OR near/lat+lon, not both.
near	string	no	A place to search around, when the question is "the nearest X" rather than "X in Y". Use with radius_km.
lat	number	no	Latitude of the point to search around, when the caller already holds a coordinate.
lon	number	no	Longitude of the point to search around.

Looks up a street address: its coordinate, and the named OpenStreetMap objects at it (company, shop, office) or that none are. Use when the person gives a STREET AND NUMBER — "Bahnhofstraße 12, Fulda" — for the point, or for who or what is there. The coordinate passes to any other tool as lat/lon.

Turns a coordinate into words: the nearest address, settlement and motorway junction with their distances, and the Gemeinde, Kreis and Land the point lies in. Use when you already HAVE a lat/lon and need to say where that is. Do NOT use to look up a place or address BY NAME — that is find_place, find_poi or find_address; this only goes coordinate to words. Those three come from the municipality th

Overview of what is around a place or coordinate: nearby fuel stations, EV charging, parking, the nearest railway station and motorway junction, each with its distance. Use when someone asks "what is around me" or "what is near <place>" — a broad look, not one category in depth.

eva_no	string	no	The station's EVA number (6–8 digits, e.g. 8002549 for Hamburg Hbf), when a previous result gave you one. It skips the name lookup and is exact — use it to answer a follow-up about a station this tool
when	string	no	Start of the window as an ISO-8601 instant with an offset ("2026-09-20T18:30:00+02:00"). Leave it out for "now", which is what almost every question means. Times in the answer are Europe/Berlin whatev
duration_min	integer	no	How far ahead to look, in minutes (5–120, default 60). Use a small window for "what leaves now" and a larger one for "this evening". Above 120 is refused: a departure board is not a timetable search.
limit	integer	no	How many departures to return, earliest first (1–15, default 10). More than 15 is refused — that is a board a person can read, not a dataset.
categories	array	no	Keep only these train types, when the person named one: "ICE", "IC" (also EC, ECE, Railjet, Nightjet), "RE" (also IRE), "RB" or "S" (S-Bahn). "next ICE to …" is ["ICE"], "Fernzug" is ["ICE", "IC"], "R
language	string	no	Set this on every call to the language the person is writing in: "en" if they wrote English, "de" if they wrote German. Do not leave it out: it defaults to German ("de"), which is only the fallback wh

Scheduled departures from any German stop — bus, tram, U-Bahn, S-Bahn, train, ferry. Use when asked when a bus, tram, U-/Stadtbahn or ferry goes ("welche Bahnen" at a Hbf too), or for another DAY or a time over 2 h away: "Wann fährt der nächste Bus ab Fulda Bahnhof?" Do NOT use for a railway station's trains now or later today — get_train_departures. Plan times, with a live delay or cancellation p

Parameter	Type	Required	Notes
stop	string	no	The stop, as the person says it: "Fulda, Bahnhof", "München, Marienplatz", "Köln, Hbf", "Hamburg, Rathausmarkt" (town first). Include the town when the person did — half the names in Germany exist in
stop_id	string	no	The stop's timetable id, exactly as a previous result of this tool gave it ("de:06631:1234"). It skips the name lookup and is exact — use it for a follow-up about a stop this tool has already named, a
when	string	no	Start of the window as an ISO-8601 instant with an offset ("2026-10-02T07:30:00+02:00"). Leave it out for "now". Convert the person's words yourself — "morgen früh", "tonight" — and pass the instant;
duration_min	integer	no	How far past that moment to look, in minutes (5–1440, default 60). Small for "what goes now", a few hours for an evening. To look further ahead (the timetable reaches at least 48 h), move when inste
modes	array	no	Keep only these kinds of service: "bus", "tram", "subway" (U-Bahn), "rail" (every train, including S-Bahn and regional) or "ferry". Omit it unless the person named a kind — "nur Busse", "welche Tram".
limit	integer	no	How many departures to return, earliest first (1–15, default 10). The result always says how many more were in the window.
language	string	no	Set this on every call to the language the person is writing in: "en" if they wrote English, "de" if they wrote German. Do not leave it out: it defaults to German ("de"), which is only the fallback wh

Report whether the lifts and escalators of a German railway station — or of a Köln Stadtbahn stop — are working now: each one, where it is, its state (in service / out of service / unknown) and the operator's explanation. Use when asked about step-free access or a broken lift: "Funktioniert der Aufzug am Kölner Hauptbahnhof?", "is the lift at Hamburg Hbf working?", "Rolltreppe am Neumarkt kaputt?"

Parameter	Type	Required	Notes
station	string	no	The railway station — or Köln Stadtbahn stop — as the person says it: "Köln Hbf", "Hamburg Hbf", "Munich Central", "Neumarkt Köln". Pass their words — English names and "central station" are understoo
eva_no	string	no	The station's EVA number (6–8 digits, e.g. 8000207 for Köln Hbf), when a previous result — a departure board, for instance — already gave you one. It skips the name lookup and is exact.
facility	string	no	Which equipment to report: "elevator" for lifts only, "escalator" for escalators only, "any" for both (default). Pass a value only when the person named the equipment itself ("Aufzug", "Rolltreppe", "
limit	integer	no	How many facilities to list (1–50, default 20). Out-of-service equipment is listed first and the counts in the summary always cover ALL of them, so a shorter list never hides a broken lift.
language	string	no	Set this on every call to the language the person is writing in: "en" if they wrote English, "de" if they wrote German. Do not leave it out: it defaults to German ("de"), which is only the fallback wh

Opens a watch so THIS conversation is told when something changes: a road reopening, a stop running late, a weather warning, a charge point turning free. Use when asked to be told later: "sag mir Bescheid, wenn die A8 wieder frei ist", "tell me when a warning comes for Kiel". A name is enough as the key; no lookup first. Do NOT use to look up now, nor for e-mail, SMS or any alert outside this chat

kind	string	yes	What kind of thing to watch. road = one motorway or federal road (key: "A8", "B27") — reports a closure or restriction appearing or clearing; station = one public-transport stop (key: its name, "K
key	string	yes	The thing to watch, in the person's own words — a name is enough and no read tool is needed first; the server resolves it and the answer names the key it resolved to. road: a road number ("A8", "B27
hours	number	no	How long to watch, in hours (default 3, maximum 24). Prefer this over until: it needs no knowledge of the current time. Give one of hours or until, never both.
until	string	no	An explicit end instant as ISO-8601 with an offset ("2026-09-20T18:40:00+02:00"), at most 24 hours ahead. Use only when the person named a time; otherwise use hours. Give one of hours or until,
condition	object	no	Optional threshold; the keys of each kind, with an example: road {"event": "reopen"} (only the reopening); station {"delay_min": 20}; region {"late_share": 0.3, "delay_min": 5, "min_trips": 20}; place

Ends a watch this conversation opened with watch_situation, so no further notifications arrive for it. Use when the person no longer needs to be told — "du musst mir nichts mehr zur A8 sagen", "stop watching that charger". No id at hand: pass kind ("weather") and key in the person's words ("A8", "Bamberg", "Kiel"); one match is stopped, several are listed. Do NOT use to look a situation up (call c

watch_id	integer	no	The numeric id of the watch to stop, as watch_situation returned it (the 12 in viafrei://watch/12).
uri	string	no	The watch's resource uri, e.g. "viafrei://watch/12". Give either this or watch_id, not both.
kind	string	no	Instead of an id: the kind of watch the person means, as watch_situation took it ("road", "station", "region", "place", "weather", "charger"). "Turn off the charging alert" is kind "charger" alone.
key	string	no	Instead of an id: the watched subject in the person's words, as it was given to watch_situation — a road or place ("A8", "Bamberg"), and with kind a place for a weather or charger watch or a stop na
